BRACELET-LOCK. I

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed ctober 24, 1916. Serial No. 127,415.

To all whom t may concern:

Be it known that I, EDMUND R. NnELiNG, a citizen of the United States,and a resident of the city of New York, Woodhaven, borough of Queens, inthe county of Queens and State of New York, have invented a new andImproved Bracelet-Lock, of which the following is a full, clear, andexact description.

My invention relates to a lock for bracelets. The object thereof is toprovide a lock which cannot be accidentally operated and therebyunlocked. u

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists inthe'novel construction, combination and arrangement of parts as hereinfully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a top plan view of the socket, certain parts of which arebroken away to show the details of construction;

Fig. 2 yis a top plan view of the stud plate cooperating with the socketand complementing the same to form the lock;

Fig. 3 is a side view of the stud plate;

Fig. t is a section on line 1 -4, Fig. l;

Fig. 5 is a bottom plan view of the socket, the slide or bolt beingshown in a different position from that shown in Fig. 1;

Fig. v6 is a section on line 6 6, Fig. 5;

Fig. 7 is a cross section similar to Fig. 1, the stud plate being shown'in engagement with the socket and locked thereto by the slide;

Fig. 8 is a section on line 8 8, Fig. 5;

Fig. 9 is a section on line 9-9, Fig. 1; and

Fig. 10 is a perspective view of the slide or bolt.

Referring to the drawings, the socket 11 is in the shape of a shallowcasing the contour of which may vary in accordance with the shape of thebracelet to which it is to be attached. The socket is preferably open atthe end where it ,is provided with a loop 12 by means of which it isattached to the structure of the bracelet. A pair of parallelly-spacedstrips 13 are provided within the socket to extend from the front to therear edges thereof. These strips reinforce the top and bottom of thesocket and constitute the guides for a slide or bolt 14 for which thefront edge has an opening, through which opening the lid 15 of the slideprojects toforma grip for manipulating the slide. The movement of theslide in the socket is limited by the engagement of a slot 16, providedvin the bottom of the socket, with a pin 17 provided in the slide.

The top of the soc'ket is rendered yielding and rmade to bear on to theslide 14 so that the friction between the two is increased and,consequently, a greater effort is necessary to move the slide from theposition shown in Fig. 1 to that shown in Fig. 5. To further assure thedifficulty of an accidental displacement of the slide in the socket, theslide isprovided in the bottom thereof with a groove 18 which is engagedby a projection 19 provided on the bottom of the socket. Thisprojectionsnaps into a depression 20 in the groove 18 when the slide isfully engaged in the socket, and in which position there will be butslight possibility of displacing the slide accidentally.

The socket 11 has a pair of spaced openings 21 traversing the top andbottom of the socket. Each opening severs the adjacent strip 18 into twoparts so that a portion of each of said openings is obstructed by theslide 14 (see Fig. 1). The slide is provided with circular recesses 22adapted to clear the openings 21 when the slot 16 and the in 17 preventa further outward movement of the slot (see Fig. 5).

In this position the stud plate 23 may be engaged to the socket as thestuds 24 of the plate are spaced so as to enter the spaced openings 21in the'socket. To lock the stud plate to the sockets, the studs 24: arenotched to allow an inward movement of the slide 14 while the studs arein the opening 21. The notches 25 are preferably arcuated so that thereis a wedging action between the slide and the stud. This action furtherincreases the resistance to an accidental displacement of the slide whenit is pushed home, as shown'best in Fig. 9. The stud plate is providedwith suitable means whereby it may be attached to the'braceletstructure; and it is self-evident that the shape of this plate, aswellas the shape of the socket, will vary in accordance with the design ofbracelet with which it is to coperate.

I claim:

1. In a lock of the class described, a socket in the shape of a shallowcasing, a slide in said casing' presenting alip at one edge thereofwhereby the slide may be manipulated in said socket, means limiting themovement of the slide in the socket, said 'casing having' an opening`and said slide havinga circular notch adapted to register with saidopening' in a predetermined position of said slide, and a plate having astud for engaging' the aperture of the socket, said stud being notchedto clear the way for the movement oi' the slide in the socket wherebysaid plate may be locked to the socket, said socket having' yieldingmeans for engaging the slide to oiier a greater resistance to themovement of the slide in the socket, said socket and slide having'coperating means influenced by the yielding' means of the socket tooffer a greater frictional resistance to the slide when the same in thesocket.

2. In a lock of the class described, a socket in the shape of a shallowcasing, parallellyspaced guiding strips in said socket, a slide in thesocket l0uided by the strips, said socket having a pair of spacedopenings, each of said openings severing' a guiding is fully engagedstrip, said slide having' a notch at each of its longitudinal edgesadapted to register with a corresponding opening' in the socket, meanslimiting` the movement of the slide in the socket whereby the notchesmay be brought into register or out of register with the openings or'the socket, said slide having' a groove, said socket having a projectionengaging' the groove, said projection normally forcing' said slideagainst the top oi" the socket, said socket having' the top thereofyielding to increase the resistance to displacement ot the slide in thesocket, said groove in the slidehavinga depression at one end thereot1adapted to be engaged by the projection under the action of theyieldingr top and thereby further increase resistance to thedisplacement of said slide in the socket, and a plate having' spacedstuds adapted to engage the apertures in the socket, each ol" said studshaving a notch for clearing the slide whereby said slide may be movedwhile the studs are engaged in the openings of the socket, therebylocking' the plate to the socket.
